Touchscreen gaming has shown us that designers can create surprisingly deep experiences out of very basic interfaces, and An Alien with a Magnet is proof positive of this.

Your only input is holding your finger down on the screen - an act which causes the titular extra-terrestrial to deploy his magnet and latch onto - and then orbit around - any nearby planet.

Releasing your touch launches him into space, and this mechanic is used to progress through each of the game's levels. Planets are surrounded by stars and gems, the latter of which are used to unlock pathways on the game's massive, branching game map.
